As a consequence, no matter how you implement the controls, you will find that in some orientations the camera rolls strangely, because the effect of trying to do the math with this information is that every frame the roll is picked/reconstructed based on the pitch and yaw. Two numbers can represent a look-direction vector but they cannot represent the third component of camera orientation, called roll (rotation about the “depth” axis of the screen). There are many differences between Zula and other similar games, but it is definitely worth playing just for the unique style of game play and beautiful art work.The problem is that two numbers, pitch and yaw, provide insufficient degrees of freedom to represent consistent free rotation behavior in space without any “horizon”. As the game progresses, you'll also see how the youths transform into more organized and lethal fighting forces, while facing new challenges along the way. As one progresses through the game, one will discover the differences of these two groups as they fight to achieve their goals. One of the themes of the game is the struggle between the good citizens of Zula and the criminal gangs of Spain.

The Zula gang uses intimidation, weapons, explosives, and C4 to intimidate their competition, while using their superior intellect and skill to plan strategies and attack with precision. As the story goes, a group of youths from an impoverished area of Spain join forces with a street gang to take over a drug trafficking route in the city. Zula was created by a group of Colombian game developers who wanted to create a free shooting game that features true urban combat. As part of the Zula organization, its members are disciplined fighters with superior weapons and an uncanny ability to improvise and develop strategies. Zula has an unbreakable code of honor, never lying or cheating, that forces players to play their part.

The gamer is forced to choose between two drastically opposed sides. It's set in exotic places like Istanbul, northern Iraq, and Paris. Zula is free to play first person shooter game available on the internet.
